    FAQs

    How can I maintain my flat roof?

    You should inspect your roof twice a year, ideally after rain or snow, to see if it’s draining properly. Also in the Spring to check for damage that may of been caused over the winter months that will need to be put right before the next winter. Have an inspection carried out if you are unsure.

    how much is a new flat roof?

    How Much Is A New Flat Roof

    What is a home without a roof to keep out the elements? Being the first line of defence against intense sun, rain, wind and more, implies they require enough care and attention to keep them in a top condition. Therefore, whether you need a new flat roof or just to replace some tiles, you’d be interested in knowing how much it would cost you to get a new roof before you start making the necessary plans. Here, we’ll give you an idea on the cost of a new flat roof and how you can estimate yours based on your unique requirements.

    The size of your roof as well as the material to be used are the two main determinants of any flat roof project’s cost. For instance, a four bedroom detached home’s slate roof will be more expensive than a felted flat roof for a small or standard garage. Generally, in the UK, the average cost for replacing a flat roof will range between £5000 to £6000. However, if you’re on a tight budget and looking for the cheapest possible option, you’ll get a felt flat roof only on a garage at about £1000 to £1500. Meanwhile if you want to replace the entire slate tiles of a large family home, the cost can jump up to a range of £11000 to £13000.

    Other factors that plays a key role in the determination of a new flat roof’s cost includes the location, labour as well as materials. For instance, a new flat roof price is likely to be higher in London and the south east than the other regions of the country. Also, labour may cost you around £150 to £250 per worker on a daily basis.

    How long should a flat roof last?

    It depends on the material you use, but if your flat roof is installed correctly it should last for at least 10 years, and at least 20 if a material other than felt is used. Always question a roofing company when they quote to find out what materials they use and what guarantee's they offer.

    how to replace a flat roof?

    How To Replace A Flat Roof

    Is it high time you replaced your flat roof with a new one? If it’s time, then you probably shouldn’t waste another minute! Flat roofs come with multiple upsides and happens to be a lot more affordable than many other options (especially for starters). Not only do they add to your home’s curb appeal and requires a relatively low labour costs as there are minimal risks involved, but they’re also more accessible for maintenance purposes and aren’t as exposed to damage as a pitched roof. However, we’re not here to discuss the various benefits of installing a flat roof, but rather tell you how to install one. If you lack proper training and experience, we’d recommend you hire a trustworthy professional that can guarantee the best results.
